You have to compile the igb driver with the IGB_LEGACY_TX path enabled for
ALTQ to work.
see sys/modules/igb/Makefile
# IGB_LEGACY_TX will override the stack if_transmit path and
# instead use the older if_start non-multiqueue capable interface.
# This might be desireable for testing, or to enable the use of
# ALTQ.
#CFLAGS += -DIGB_LEGACY_TX
If you are going to rebuild the kernel and not just the module, changing
CFLAGS in the module Makefile or anywhere else that I've tried will NOT
work. The only way I've found to work is to add a #define to if_igb.h and
if_igb.c directly.
You can do this by defining IGB_LEGACY_TX in sys/dev/e1000/if_igb.c
and sys/dev/e1000/if_igb.h.
I use the following little shell script to do this:
echo 'Performing IGB_LEGACY_TX mod'
cd /usr/src/sys/dev/e1000
for ext in c h
do
echo '#define IGB_LEGACY_TX' > if_igb.$ext.new
cat if_igb.$ext >> if_igb.$ext.new
mv -v if_igb.$ext.new if_igb.$ext
done
echo
FreeBSD really needs to add some official documentation on how to use ALTQ
with igb and ixgbe, as it has been a persistent issue for myself and others
since 8.x.
There is a bug/PR to make the IGB_LEGACY_TX path a proper kernel option,
instead of having to modify the driver directly.
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=194197.
Maybe you would have some luck trying that patch and adding the options to
your kernel conf and rebuilding.
